IMPROVEMENT IN SASH-FASTENERS.

Specification formingpart of Letters Patent No. 202,154, dated April 9,1878 application filed February 21, 1878.

To all whom it may concern Be it known that I, OSBORN R. 000m, ofChicago, in the county of Cook and State of Illinois, have invented anew and useful Improvement in Sash-Holders, which is fully described inthe following specification, reference being had to theaccompanyingdrawings, in which I v Figure 1 represents an insideelevation of a windowframe and sashwith my improved holder applied; Fig.2, an edge. view of the same, taken on the line as m, Fig. 1; Fig. 3, aplan view of the holder and rod attached; Fig. 4, a similar view of thebottom of the same; Fig. 5, a plan view of thegkeeper for the lower endof the clutch-rod, with the latter in place; Fig. 6, a detail view ofthe lower end of clutch-rod; Fig. 7, an edge view of the boxframe,showing the clutch-rod in place; Fig. 8, an edge view of the sash nextto the glass, with the holder applied; Fig. 9, a similar view of theopposite .edge of the same; Fig. 10, a plan view of one of the dogs orclutches; and Fig. 11, a similar .view of the catch-spring. I I

My invention relates to an improvement upon the sash-holder shown anddescribed in Letters Patent No. 129,774, granted July 23, 1872. 1

-In the patent aforesaid the holding-catch is attached to thesash-frame, and is consequently stationary, while the rod in connectionwith which it operates is attached to the sash and moves up and downwith it.

In my improvement I-attach the rod to the frame, making it stationary,and mount the dogs or catches on the sash, by which arrangement I amenabled to improve and simplify the construction and operation of thelatter.

The invention consists in a rod attached to the window-frame, incombination with a pair of spring dogs or catches attached to the sash,and arranged to bite at one end on the rod, along which they are free tomove when their outer ends are pressed together.

It also consists in a special device for holding the rod in place in theframe, by means of which it is secured in place, but at the same time isdetachable.

It also .consists in the special construction of other devices, all ofwhich will be hereinafter more fully set forth.

In the drawings, A represents a windowframc, and B the sash. A rod, 0,is attached to the box-frame, so as to project out therefrom toward thesash, as shown in Fig. 7 of the drawings. The ends of this rod are bent,and the lower bent portion 0 is flattened, as shown in Fig. 6 of thedrawings, so that it is wider and thinner at its extremity than anywhereelse. A hole, a, is made in the box-frame for the upper end of the rod0. The lower end is held by akeeper, D, inserted in a recess near thebottom of the frame, and provided with an elongated slot, d, at itslower end. This'slot is made of such width that it will only receive thelower bent end of the rod when turned up edgewise, and the rod 0 isplaced in position by first inserting the bent lower end into the slotofthe keeper, as shown by dotted lines in Fig. 5 of the drawings, thenturning it up, as shown in full lines in the same drawings. andinserting the upper end in the hole a, the latter being preferablyarranged at a distance from the upper end of the slot in the keeperabout equal to the length of the rod. It will thus be seen that thelower end of the rod cannot be removed from the keeper until turned downagain, and, as the other end is up out of the way, the rod will be heldin place and cannot be easily disarranged. i

The outer edge of the sashis provided with a longitudinal groove, 11,which receives the rod 0, so that the latter will not interfere with theraising and lowering of the former.

Two catches or dogs, E, are arranged within a recess in the side of thesash upon the inside of the latter, and are provided at one end withapertures e, which are adapted to receive the rod G on which the catchesare placed. The catches are also provided with central apertures 0,extending in an opposite direction to those in the ends. A shield, F, isfitted to cover the recess within which the catches are placed, and isattached to the sash by screws, one of which passes through a centralopening, f, and the central apertures c in the catches, thereby securingthe latter in place and forming a pivotal bearing for them. The outerends of the catches are bent outward at right angles, as shown in Fig.10 of the drawings, and extend outside of the shield, and are enlargedto form thumb-pieces p F is also provided with a projection, f upon Vsired to raise or lower the sash.

E, in which recesses, 6 are cut to receive the inner edge of the shield.The inside faces ofthe thumb-pieces have shallow grooves 0 which areadapted to receive the free ends of a spring, Gr, having a coil, g, atits center, as shown in Fig. 11 of the drawings. The shield its outerface, which is arranged between the outer ends or thumb-pieces of thecatches.

When the catches are placed within the recess in the sash, the spring Gris arranged in position between their outer ends, as shown in Fig. 8 ofthe drawings, so that when all the parts are arranged and secured to theframe and sash, as hereinbefore described, this spring will operate tospread open the outer ends of the catches, thereby spreading apart theinner ends also. But the rod 0 passes through the inner ends of thecatches, and the holes in the latter pass directly through, so that theywill slip readily on the rod only when brought together. Hence, wheneverthese inner ends of the catches are. forced apart, as by the springabove described, they will bite upon the rod, and prevent the sash frombeing moved in either direction. -At the same time the pivotal catchesmay be vibrated by means of the thumb-pieces E, so as to bring theirinner ends together, and permit them to slip upon the rod whenever it isde- The device is extremely simple and very efiicient, furnishing ameans not only for preventing the sash from dropping, but for looking itagainst movement from the outside in either direction. The parts are noteasily dis-arranged, and the slight wear occasioned by friction on therod does not impair the efliciency of the catches.

Instead of a spring, the dogs may be weighted, in which case it isevident that the weights must be arranged upon opposite ends of the twocatches-i. 0., the weight must be upon the lower outer end of one catchand upon the lower end of the other, in order to make them gripe the rodwhen released. The springmay be used with such weighted catches, ifdesired and found necessary. The form of the spring may be changed, iffound desirable for efliciency.

Instead of a screw passing through the shield and catches, a stud-pinmay be cast on the inside of the shield to form the pivotal support forthe catches; and in this construction it will be necessary to cut awaythe thumb-pieces somewhat, as shown in Fig. 10 of the drawings, topermit the shield to be adjusted properly to insert the pin in thecentral openings of the catches. This style of holder is adapted to thelower sash of the windows of houses; but is not so convenient for uppersash, for it is evident that the device must necessarily be located nearthe upper end of the sash, and therefore could not be easily reached. Itis also well adapted for use upon car-windows, and in other like places.i

I do not limit myself to the precise form I and arrangement of all theparts herein described and shown,- for changes may be made to someextent without materially afiecting the principle of operation ashereinbefore described. 7

Having thus described my invention, what I claim as new, and desiretosecure by Let- ;ters Patent, is-

1. An upright stationary rod, 0, attached to the window-frame, incombination with a pair of catches or dogs pivoted to the sash, withtheir inner ends embracing the rod, and

constructed and arranged so that when these ends are closed togetherthey will slide freely on the rods, and when opened will bite or gripethe latter in opposite directions, substantially as set forth.

2. The stationary rod C attached to the window-frame, in combinationwith the sash B, having a groove, 12, the pivoted catches E, and aseparating-spring, G, substantially as described.

3. The shield F, provided with a projection or stop, f, in combinationwith the pivoted catches E and the spring Gr, substantially asdescribed.

4. The bent rod, 0 having its lower bent end flattened and widened, asspecified, in combination with the keeper D, provided with an elongatedslot, 01, substantially as described.
